Captain Eoin Morgan recalled the worry he experienced after suffering concussion symptoms as a result of a Mitchell Starc bouncer, but insists he is fully fit ahead of England's one-day series against Pakistan.
Morgan took a short delivery square on the side of the helmet from Starc in the final ODI against Australia in September and his only time in the middle since then came in a warm-up fixture against Hong Kong on Sunday.
The 29-year-old watched the incident back and insists it was a good delivery from the Australia paceman, while stating he has been working hard in the nets to guard against the short ball in the future.
"At the time it was quite concerning, the ball hit me hard," he said.
"It was a good delivery, I look back at it now and it was a good delivery. I've done a lot of short-ball practice since and I'm confident I've progressed in that manner.
"It was about 10 days before I was myself, in terms of balance, grogginess, and it was just a really weird feeling.
"It's worrying to be honest because the feeling of concussion is something I've never had before. Being in that position having never been in it before worried me a lot.
"But you start building confidence up in the nets. I started doing that in the nets two or three weeks ago. It's crucial, as long as I'm feeling alright, which I am, I know guys have had concussion for prolonged periods and I feel very lucky to be back this soon."
Morgan, who will skipper the team in the first of four ODIs against Pakistan in Abu Dhabi on Wednesday, revealed that he changed helmets during the Australia series and has since upgraded again.
"I did change it during the series," he added. "I got hit on the neck at Lord's and wasn't wearing a neck-guard, so I changed to a Masuri helmet.
"I feel more protected with the neck-guard that they have, so I went for the full helmet.
"I've since had scans on my head to have a mould for my own helmet, which I'm wearing now."
